Long Combination Vehicle (LCV) Program

The Long Combination Vehicle (LCV) Program supports the efficient movement of goods across the province and beyond.

A typical LCV is up to 40 metres long, consisting of a tractor pulling two full-length semitrailers. A standard LCV replaces two 23-metre tractor-trailers.

MTO gradually introduced LCVs onto Ontario roadways by issuing a limited number of permits to a limited number of carriers. This has allowed for a carefully controlled and closely monitored program as part of an effort to build a stronger, greener economy.

The Canada Safety Council reports that LCVs are involved in at least 40% fewer collisions than regular tractor-trailers.

Economic Benefits

  • LCVs are good for manufacturers and consumers. They allow Ontario retailers and manufacturers to bring light-weight, bulky goods to market at a lower cost.

Environmental Benefits

  • By using less fuel to carry goods, LCVs reduce the greenhouse gas emissions (GHGs) associated with shipping goods by approximately one-third.


  • LCVs have been on the road in Western Canada, Quebec, and numerous American states for decades. They have an excellent safety record, with fewer collisions reported than single-trailer trucks.
  • A major study of LCV operations in Alberta showed that LCVs of the type allowed in Ontario had 60 per cent fewer collisions than the conventional tractor-trailers they replace.
  • As each LCV replaces two conventional tractor-trailers, the number of collisions is expected to be reduced by 80% as compared to moving the same freight by conventional tractor-trailer.

Requirements and Restrictions

Rules for LCVs include that they:

  • Can only operate on designated divided highways (primarily 400-series highways).
  • Can only access destination terminals within two kilometres of highway interchanges, and only if routes have been carefully assessed and approved.
  • Must have special safety equipment, including enhanced braking requirements and an electronic stability control system.
  • May not drive in or through the Greater Toronto Area or the City of Ottawa during rush hours.
  • May not carry more weight than existing multi-axle tractor-trailers.
  • May not operate at the start and end of long weekends.
  • May not carry dangerous goods that would require a warning on the vehicle's exterior.
  • May not carry livestock.
  • Must avoid driving in bad weather or slippery conditions.
  • May not exceed 90km/hr.

Special requirements for LCV drivers include that they:

  • Must be experienced tractor-trailer operators with a good safety record.
  • Must obtain and carry an LCV Driver’s Certificate based on specialized and comprehensive training and road testing.
